Hint: you can still see the onld screen with new permissions marked as NEW by scrolling all the way down in app description to PERMISSIONS and clicking on"View details".

But I completely agree with you. Totally lame move by Google. I want to see this screen when I press the update button. Config option for advanced users would be sufficient.

Gentoo doesn't keep the source in the repository, but it has the hashes.

Did you actually measure it (adrobench storage read/write test for example) and did not find any difference?
I'm assuming not and since Nexus 5 is fast to begin with there isn't any *noticable* difference.

Only recently (KitKat release) Google added TRIM support for encrypted volumes. Without that the performance difference between unencrypted (with TRIM) and encrypted (no TRIM) was very noticable after device was used for some time.
Unlucky for owners of older devices (1st gen Nexus 7, Galaxy Nexus) it does not work. This problem is very serious on 1st gen Nexus 7, to the point where it becomes unusable if encryption is used: https://code.google.com/p/andr...

No, android does not have full device encryption unfortunately. Only the encryption of /data partition. In most cases this should be sufficient though.

I'm not sure about external sdcard for devices that have it. I have Nexus so emulated sdcard is part of /data and it gets encrypted. If that is not the case with external sdcard, tough luck.

Also, doesn't look like google particularry cares about older devices and device encryption. See this issue for example (TRIM support on encrypted volume): https://code.google.com/p/andr...
I'm not holding my breath to ever get this resolved for my 1st gen Nexus 7.

You can disable this "feature" with a hammer. It's pretty straightforward and I've done that with my Visa Paywave cards. Punching the hole will also work but I'm not sure if such card will be accepted by merchants.
If your credit card has both RFid (like Visa Paywave) and chip/pin contacts, destroying RFid chip will also most likely destroy chip/pin interface because they would likely be packaged on the same chip.
